Warp Flutes
Warp Flute 1: In world one, level three, go near the end of the level until you see a white block. Step onto this white block and duck, and after a while you will fall behind it. Stay behind the backround while going all the way to the end of the level.

Warp Flute 2: In world one's fortress, go to the area where the ceiling is open (it is just before a door with a skeleton koopa). Make sure you have a raccoon leaf. Fly up above the screen and then move to the end at the right. There should be a hidden doorway.

Warp Flute 3: In world two, go to the top right corner of the map. Use a hammer to break a boulder up there, and then continue to the right to find a hammer brother. Beat him to get the flute.

Special Suit Trick
Go to a mushroom house and pick a chest. If it contains a suit, get a game over. Now select continue. The levels you have beaten will not be reset, only the mushroom houses and the slot machine games. After continuing, go back to the same mushroom house where you've received the suit. No matter what chest you pick, you will always find a copy of the same suit. Repeat this trick to get as many suits as you want.

Underwater Shortcut
There is an easy way to beat the ship level (after the tank level) in the final world. Just swim under below the ships. Keep pressing A so you won't sink too deep and die.

Warp to World 8
Once you've got two warp whistles you can use them both to instantly end up in World 8.

Lots Of Lives
First go to level 1-2. Go about half-way through the level until there is a pirana plat by some coins in the air. Below the plat there are two bricks, smah the one with the P block and smash it. While the coins are bricks, run up and go to the right of the pirana plant. Jump and a 1-Up mushroom will pop up. Quickly grab the mushroom and go into the tunnel. When you come out of the tunnel, do this process over and over until time runs out and you will have a bunch of lives.

Secret Room In World 8-2
To find the secret room in world 8-2, go to the first sinking sand, go in it and let your self sink. When you at the bottom you will see your self in a secret room with two pipes. Both pipes lead to different rooms. After you get out of one of the pipes you just went in, you will end up near the end of the level.

Defeating Roto-Discs
To defeat a Roto-Disc you will need to be wearing a Tanooki Suit. After you have got a Tanooki Suit, find a Roto-Disc and make it so that it is underneath you. Right before it hits you quickly turn into the statue by holding the Down and B button. Once it hits from underneath you as a staue, the Roto-Disc will be defeated. Incase you don't no what a Roto-Disc is, it's the diso balllike enemy that rotates around a metal ball.

Defeating The Angry Sun
To defeat The Angry Sun, you must be wearing the Hammer Suit. Once you are wearing the Hammer Suit, throw a hammer at The Angry Sun and it will die.

Finding White Mushroom Houses
If you get enough coins in certain levels, you will find a White Mushroom House back on the map. Here are the minimum amount of coins you need to pick up at the following levels:

The White Mushroom Houses in Worlds 1, 3, 5, and 7 give you P Wings, while the White Mushroom Houses in Worlds 2, 4, and 6 give you Anchors.

Life Swapping
This trick is only done on Mario and Luigi Mode. To do this trick find a small m or l on the map screen, press the A button on it and start swapping lives using the controll pad. Then press the B button to get out.

No More Dry Bones
To make Dry Bones disappear, make him into a pile of bones and the walk across the screen until you can no longer see him. Then go back and he will be gone.

Selecting Worlds and Redoing Levels
Once you've deafeted Bowser, you can select your own world and redo the levels you've beaten in the past, but you can't redo fortesses and castles.

Secret Warp Whistle In Fortress 1
To do this you need to have a Racoon Suit. Once you have the Racoon Suit, go near the end of the first room you appear in. At the end of the room, you should see a door and a Dry Bones. Quickly take out the Dry Bones and go near the door and run so you can fly until you can no longer go up. While you're in the air, keep going right until you end up in a room with a small chest holding a Warp Whistle. Once you have the Warp Whistle you will not have to fight Boom, Boom. (the boss of the fortress)

star panels
every time you are about to beat the level, run as fast as you can so the "P" at the bottom is blinking. Then, jump into the block and you will get a star. Get 3 stars and you will get 5 lives.
